I recently subscribed to chat gpt plus . I said it was 29.99 aus . When I made the payment , my invoice showed 32.98 aud.. why am i paying the extra 3 aud?

Possible conversion differences or else some other fee tacked on like taxes. Probabky GST

Thank you for your response …Nah … if converted it would have been 42 aud. But don’t you think the price has to be transparent they should include 32.98 instead of 29.99 aud
